JOINTING-HEAD roe WOODWORKING-MAGHINES.

To all whom it may concern j Be it known that LJnssn W. FosTERL Nc,

a citizen of the United States, residingat Missoula, in the county of Missoula and State of Montana, have invented certain new and useful Improvements in Jointing-I-I'eads for Woodworking-Machines, of which the following is a specification, reference being is capable of various adjustments whereby to be applied to use in connection with jointer heads of various shapes and sizes.

A further object of the invention resides in providing a jointer, the base member of which is capable of adjustments on a member carrying the same and a still further characters designate corresponding parts object resides in providing a grinding mem her which is capable of various adjustments with respect to the base member.

Still another object'of the invention'resides-in providing a device which is simple and durablein construction, inexpensive to manufacture and one which will be very efficient and usefulgin operation.

With these and other objects in view,the invention consists in the novel features of construction, combination and arrangement of parts as will be hereinafter referred to and more particularly pointed out in the specification-and claims.

In the accompanying drawings forming a part of this application, Figure lis a plan View of a device constructed in accordance with my invention, showing the same applied -to use. Fig. 2 is .a side elevation thereof. Fig. 3 is a section as seen on line 3.3, Fig. 2. Fig. 4 is a perspective view of one of the post members used on the device. Fig. .5 is a similar view of the movable strip member carried in the channel of vation of a slightly modified form of the invention. 3 r

. In describing myinvention, I shall refer to the drawings in which similar reference throughout the several views and in which 1 indicates, what is known in wood working machines of this character, as a chip breaker plate and 2 the jointer head. In this particular head the chip breaker plate Specification of Letters Patent.

minating at its one endinan enlarged recess 4L, 'and the one side wall of' the-slot 3 1s beveled outwardly fromits upper to its Removably from the front face of the body and forms a bearing'post as will be hereinafter and, more particularly setfforth. Removably se curedin position on the front face of the bodyQ and inthe side of the channel "or slot opposite that side which is'beveled, is a strip 7 which has its inner side edge beveled coincident to the, beveled side 5 of the slot or channel 3, and this strip extends substantially the full length of the slot to the en'- larged recess, thus providing substantially .a dove-tail channel or slot. Slidablymoimted in this slot between-the strip .and the beveled side wall of the channel or slot is a bar 8 which has the side edges thereof beveled coincident to the beveled side ofthe' slot andthe beveled edge of the jistrip- '7 to fit snugly therebetween. It is obvious that the bar is positioned in the slot orchannell 3 prior to the application of the strip 7 in position and, inasmuch as this strip 7 is re-j movable and ad ustable in place,the friction :bar, as'desired, .gThe'end of the bar 8, ad-

jacent the post Gisalso provided with an angular projection 9 which is designed to,

form a post similarto the post 6 withwhich 'the same is adapted to coeperate, as will be hereinafter set forth. The'opposite end ofthe bar 8 is provided with a U-shaped projection 10 formed integral'therewith andthe' arms of which are designed to fitsnugly be tween the walls vof the enlarged recess 4.

The free ends of the arms of this U-shaped I projection are slightly enlarged to form substantially disk portions as shown'at 11 and pivotally mounted between the outer free, ends of said arms, is a block or the like .12. The one face .of this block is provided with aslot l3 and a portion of one side wall of the slot is removable, as shown at lt said wallnbeing. adjustably securedain vposltlon by means ofthe set screws 15. A stone or strip of other grinding material, indicated as 16 is designed to be held in place in the slot of this block, and in view of the construction described, it will be seen that said stone may be readily adjusted in the slot or removed, at will.

i The block with the grinding stone carried therein is adapted to be swung on its pivot into various positions for engagement with the edges of the cutters or knives and I have provided a means for the retention of the block and parts carried thereby in anyv desired position. To this end, a binding strip or plate 17 is pivotally and removably applied to one side of the block 12, said pivotal engagement being at one end of said plate or strip. lhe opposite end of said strip or plate is adapted to contact with the outer side face of the enlarged disk-like portion 11 on one arm of the U-shaped projection 10. Aset screw 18 extends through this strip or plate and is engaged with a threaded open ing in a side of the block. This set screw may obviously be adjusted for binding engagement with the outerface of the strip or plate 17 thus causing said strip or plate to bind against the outer side face of the enlarged disk-like portion 11 on the arm of the U-shaped member and, in this manner, said block may be held in any desired position. I have provided ascale in connection with this U-shaped member 10 to determine at just what angle the block may be set with respect thereto and accomplish a'desired result. To this end, the disk-like portion 11 of the arm opposite that with which the strip or plate .1? is engaged, is provided with a plurality of notches or ridges 19 which are placed thereon after certain calculations have been made. An additional notch or ridge 20 is placed on the one edge ofthe block 12 and in the movementof said block with respect to the U-shaped projection the notch 20 is adapted for registration with the notches 19. The former notch may be said to register with any one of the latter notches according to the particular angle at which the block is desired to be set to accomplish the desired result. Thus this block with a grinding stone thereonmay be set at various angles according to the particular cutters and the position thereof with respect to the jointing head.

'As stated, the post 6 is designed for cooperation with the projection or post 9 of the adjustable bar 8, said post being designed for bearing posts and said posts 6 and 9 are provided with alining openings 21 and 22, respectively. The opening 22 in the post 9 is threaded and receives in engagement therewith a threaded portion of a shank 23, the unthreaded portion of said shank also extending through the opening 21 of the post 6. A handle member 2a is suitably engaged with the outer end of the shank and through this medium it is obvious that the bar 8 with the parts carried thereon may be readily adjusted on the base or body 2. In this manner, the block carried at one end of the bar 8 may be positioned adjacent to or distant from the cutters, as desired without the actual adjustment of the block with respect to the bar, which latter requires a separate operation.

In Fig. 6, I have shown a slightly modified form of the invention, wherein provision is made for the application of the jointer to any bed or table. In the first mentioned form, it will be seen that the chip breaker plate is provided with a particular designed dove-tail channel, in which the base or body portion of the jointer is slidably and adjustably mounted. In this instance, however, the base or body is not designed for sliding adjustment within said channel-way. The base or body 25 of this particular form is provided with a downwardly and inwardly curved arm 26, the free end of which is provided with a threaded eye 27. Engaged with this threaded eye, is a threaded shank 28, the upper end of which is provided with a head or clamping jaw 29, the opposite end of this shank being provided with a handle member or the like 30. The under face of the body or base piece 25 is designed to form a clamping aw for cooperation with the head or clamping member 29 and it will be seen from this construction that the device may be quickly and readily clamped in position on any bed or table of a machine or any other preferred device.

From the foregoing description of the construction of my improved device the manner of applying the same to use and the operation thereof will be readily understood and it will be seen that I have provided an improved device which is simple and durable in construction, inexpensive to manufacture and one which will be very eficient and useful in operation.

lVhile I have particularly described the elements 'best adapted to perform the functions set forth, it is obvious that various changes in form,proportion andinthe minor details of construction may be resorted to without departing from the spirit or sacrificing any of the principles of the invention.

Having thus described this invention, what is claimed is 1.
